I had a recent discussion with a born again christian who believes that the end of times is near, and will be here within his life time. He pointed to prophesy and is looking for the mark of the beast as a clear sign that he is right. I pointed out to him that the concept of prophesy is flawed because if you know the prophesy you can undo it. For example, I tell you you will be hit by a car at three pm on tuesday and die. You stay at home and don't leave the house and consequently you don't get hit by the car. Is the prophesy true or false? it turned out to be false because you knew ahead of time what would happen, so you changed your actions and thwarted the prophesy. I told him that God had intended for us to heed the book of revelation and to change our ways before the outcome described comes to pass. He seems to believe that it will come to pass no matter what we do. If he is right what does that say about God giving us free will? As an aside I would be curious to know what everyone else thinks about this so-called "mark of the beast". I believe that people have enough knowledge about the mark that there would be no way such a law requiring the mark would ever be accepted let alone passed. Also, what is the mark interpeted to be? a tattoo, a microchip, social security number, or whatever. Where is the mark to be placed? on the forehead, hand, or anywhere on the body. How loosely is the prophesy interpeted? will any combination suffice?
